Claims
exact text as granted — not AI-modifiedI claim:
1. A xylophone comprising: a frame structure including two frame end-portions, and said frame structure including two supporting lateral frame members, said frame end-portions and said supporting lateral frame members forming a long ladder-shaped structure; each of said two supporting lateral frame members being provided with a plurality of vertical pegs and having a channel along the center line on the top thereof for mounting a respective one of a plurality of wave-shaped pads; at least one supporting lateral frame member being furnished with a plurality of small holes between vertical pegs so as to insert a respective fastening wire through corresponding holes in at least one metal tone-producing pipe; a plurality of metal tone-producing pipes, each pipe having a curved top surface, a planar bottom and vertical walls; and each of said tone-producing pipes having a small hole in registry with a respective one of said small holes in said at least one supporting lateral frame member; a plurality of wave-shaped pads, one each located between a respective pair of pegs in each channel; and for each supporting lateral frame member a protective strip, with at least one protective strip being also furnished with small holes corresponding to those holes in said tone-producing pipes; and after a respective tone-producing pipe has been put on said two supporting lateral frame members between respective vertical pegs, said small holes in said protective strips, said tone-producing pipes, and said supporting lateral frame member being aligned with respect to one another so as to let a respective fastening wire penetrate and secure said tone-producing pipes.
2. The xylophone according to claim 1, wherein said pads are foam rubber pads.
3. The xylophone according to claim 1, wherein on at least one protective strip numerical notations are marked with seven different colours to indicate the seven scale notes.
4. The xylophone according to claim 1, wherein the respectively other protective strip is fixed in place with a screw to prevent said tone-producing pipes from dropping out at that other lateral frame member.Join the waitlist — get patent alerts
